They got what they deserved, that round - the borgs had orders to set up a singulo and supermatter shard to (presumably) give teeth to the AI's eventual demands. The engiborg got caught, a party of engineers and security officers burst into the (vented) room it was using, ZAS did its thing, and before you know it the better part of a dozen people are dead or dismembered.
Then the other supermatter began to delaminate.
Sic Semper Metagamers.
while the metagaming was terrible that round, that AI tries that every round without fail just trying to stealthnuke/delaminate
